To all 'whom it may concern:

Be it known that I, MARSHALL S. SHAP- LEIGH, a citizen of the United States, residing at Glenside, in the county of Montgomery and State of Pennsylvania, have invented new and useful Improvements in Mixing-Machines, of which the following is a specification.

The invention relates to machines for mixing liquids or fluids of different densities, or a. iinid with a non-fluid substance, and which also may be employed to reduce semi-liquid or other substances or compositions to a substantially uniform consistency, or to different consistencies.

The object is the provision of a machine of the general type or class which shall effect a more thorough mixture of, or reduce to uniform consistency, or different consistencies, the liquid or liquids or substance or substances acted upon, and in a less period of time than analogous machines heretofore known.

The invention consists in certain novelties of construction and combinations of parts hereinafter set forth and claimed.

The accompanying drawing illustrates one complete example and several modifications of the physical embodiment of the invention constructed according to the best modes I have so far devised for the practical application of the principle.

Figure 1 is a view of the machine with the parts assembled, the vessel and one deflector being in section. Fig. 2 is a top plan view of the vessel or glass jar shown in section in Fig. 1, and of the spiral deflectors, collector and paddle within the jar, the cover being removed. Fig. 3 is an outside elevation view of a part of the upper port-ion of the glass jar, showing the means for securing in place the upper end of the deflector. Fig. 4 illustrates a way of anchoring the lower end of a deector to the bottom of the jar. Figs. 5 and 6 illustrate modified ways of securing the upper and lower ends of a deflector to the vessel or jar. Fig. 7 is an edge view of the collector and a top plan view of the paddle.

Referring tothe several figures, the numeral 1 designates a base piece of any suitable construction; 2, a glass ar or other suitable vessel or receptacle, preferably of circular shape in horizontal section, and held in osition upon the base by a projecting lip 3 extending around the circumference of the jar or vessel; 4, a cover made in two pieces and having a hole at the center for the passage ofV the rotary shaft-s; 5, an adjustable standard or support secured to the base, in this instance comprised of a tube Gand a telescoping tube or rod 7, the former being' provided with a clamping butterfly nut Shaving a threaded stein passed through a hole in the tube and engagingl the rod 7, thev rod being movable within the tube;v 9, a casting provided with two bearings 10 and 11 for a shaft, and with two perforated arms 12, 13, said casting being secured vto the top end of the telescoping tube or rod; 14, a' rotary shaft supported in the bearings 10 and 11 of thejcasting; 15, a. crank on the shaft; 16, a relatively large gear wheel at the opposite end of the shaft; 17, the collector made in one piece, having an opening 1S at the top and a smaller opening 19 at the bottom; 20, a shaft journaled in the arm 12 at the top and at the bottom end secured in the opening 19 by a set-screw; 21, a gear wheel on the shaft adjacent its top end; 22, a tube having a gear wheel 23 rigidly secured to its top end and journaled in the arm 13, the tube being located about the shaft 20 and extending .downwardly through the opening 18 at the top of the collector and loosely engaging the surface of theopening; and 24 a paddle with two openings 25, 26, and three blades, as shown, each having the shape of half a vcircular disk with a. semicircular edge, said tube being passed through the openings andthe paddle rigidly secured to the tube by a set-screw 27 as shown.

Thev collector is cast or fashioned in one piece and is of the shape shown, each half upon opposite sides of the shafts being of identical sha-pe, but oppositely disposed.

The numeral 2S designates the scoopsv of the collector, each concavo-convex from top to bottom. Each has a relatively narrow top portion 29v which increases in width downwardly to 30, where it perceptibly widens to form a wing 31 with a rectangular projection 32. The inner surface from 29 to 30 is dish'ed, and the wing slightly concave at 33, the rear surface 34 being slightly con'- vex, so that the liquid will be picked up at thetop, sides and bottom of the vessel and deflected' and delivered into the path of the paddle. A

Within the vessel or jar are two deflecting spirals or spiral deiiectors', 35, oppositely disposed and each extending about onefourth the circumference of the ar, curving downwardly from the top to the bottom. The upper end of each spiral is wider than the lower end, may be slightly concavo-convex in cross section, and each has a downwardly curved wing 36 with a curved under surface which prevents the liquid at this position within the jar from moving toward the center thereof. The upper end of each spiral has an extension 37 with a n shaped bend at the extreme end which laps over the edge of the jar. A thumb screw 3S with a threaded stem passed through a threaded opening in the outer arm of the n shaped bent portion may be employed to clamp the defiecting spiral securely to the inner surface of the jar. The lower end of the spiral, by reason of its shape, will generally maintain its fixed position yin Contact with the inner surface of the jar; however, it may be provided with a projecting lug 39, as shown in Fig. 4L in detail, located within a recess 40 in the wall of the vessel. The lower end of the spiral may also be held in place by a lug 4:1 projecting from the bottom of the vessel, see Fig. 6, or it may engage a recess formed in the said bottom. When a large vessel is used the wall may be perforated, the spiral be provided with one or more threaded stems passed through the perforation or perforations and a butterfly nut or nuts applied to the threaded stem or stems to hold the top end of the spiral in fixed position, as shown by Fig. 5. However, any suitable means may be employed to secure the spirals in detachable or fixed positions.

The mode of operation in a general way is as follows: The liquid or composition, or whatever it may be, which is to be treated is introduced into the jar or vessel, the cover placed in position, and the crank turned, which action rotates the shaft and collector in one direct-ion and the tube and paddle in the opposite direction. The collector picks up the liquid or other substance at the top, bottom and sides of the vessel or jar and defleets it into the path of the paddle, which latter strikes it with considerable force and by centrifugal action hurls it against the inner surface of the jar or vessel. The spiral deiectors then guide the liquid or substance "downwardly to the bottom of t-he jar and force it inwardly into the path of the collector where it is again picked up and commences another circuit. It is, of course, impossible to specifically describe the path `traversed by any portion of the liquid or jected to the action of thevmachine they are so thoroughly mixed that separation cannot be detected after a long period of time.
